It seems that this problem is not unknown; especially when upgrading to win-10...

There are numerous discussions, and suggested fixes/solutions, on the web. This is one of many:

If you repeat my trawl using:

Problem with PnP devices

as the search term (words) or string you'll see many more solutions, including the one above.

Incidentally, like many here, prefer and use duckduckgo instead of the dreaded google. It doesn't track you, nor garner (gather) information about you and both sell it and allegedly sell it on ...

Here's a link to the support page:

✔ Best Answer
I did face the same issue a couple of months back and I used the official Windows support article I found on their website, but I was not able to resolve the issue. Thankfully, I had a tech friend who was able to give me a valuable input at that time, which helped me solve this issue and I’d like to share the same with you.

• Go to ‘Device Manager’.
• Use administrator account credentials to proceed further.
• Find the PnP device you are referring to under the USB host controller panel.
• Uninstall this driver and then reboot your system.
• While rebooting, Windows would automatically re-install the driver for you.

This worked just fine for me and I hope it works for you too!
